NASA Building Giant Roller Coaster For Science 85

Posted by CmdrTaco
from the still-no-excuse-for-300ft-pinwheel dept.
Jamie found a story of NASAs Giant "Science" Roller Coaster. It will be used as an escape chute on rocket launchpads, and will be the 3rd highest drop in the world. More like the Cedar Point Demon Drop than a roller coaster, but still, I'd ride it.

    Has NASA ever had an accident where 4 minutes to escape is good enough? Most of the accidents that I've read about went "Boom" and was over, long before any escape system like this could work.

      The Apollo 1 fire would be a good example. If there was a cockpit fire and any of the crew got out, you'd want them out of the way and on the ground fast. That takes a lot less than 4 minutes.
      • How is it a good example? The crew was dead less than 30 seconds after the fire started. With the pressurized 100% O2 environment they were testing with on the pad, it was more of an explosion than a fire. They couldn't even get the capsule door open before the pressure inside pinned it closed.

      What scenario are they planning for? Shuttle has the escape wires because there is no other method of escape. (At most times during the mission, your only hope to survive a Shuttle flight is to land safely.) Orion will have a good, old-fashioned escape rocket to pull the whole capsule into the sky and parachute down. So you would use this roller-coaster to evacuate if the emergency is prior to the point where the access arm is retracted? I notice from the number of seats on the "coaster" that there are

      Given the fact that the launch tower and associated facilities for Orion will be built / modified anyway for at a cost of billions of dollars why not spend a few extra million to provide yet another obvious escape route? Heck NASA could even license the naming rights and theming for rides at amusement parks to recoup some of the costs.

      Here's another example. Suppose you're working on the CEV when suddenly there's a hypergolic leak. Even if it doesn't burst in flame, these propellants are traditionally very toxic. So you have a dangerous situation either with flames or without. Hop in the escape coaster and get out of there.

    • The thing to do when you were a kid riding the Demon Drop was to put pennies on your knees. During the initial acceleration you'll fall faster than gravity and the pennies will lift off of your knees. Then - during free fall they'll hover in front of your chest as you fall. It's a brief moment of weightlessness.

    I was at Cape Canaveral this past spring, just as a tourist. (Missed
    Buzz Aldrin signing his book by half an hour, dernit!) We took the better
    tour that let you see more of the launch pads and the construction sites.

    Anyway, the escape system they have right now is a zip line. If something
    bad is about to happen, the astronauts grab onto the harness and slide down
    a metal cable. There's a sorta-fire-proof vehicle at the end of the zip line
    ready to haul ass at a moments notice. Their instructions were to get in the
    vehicle and take off. Fast. I assume praying would also be involved. The
    guide said that MIGHT be enough to keep them from becoming BBQ, but not blowing
    up the craft is still the best strategy.

    Getting blown into space on top of a barely controlled explosion is still a
    pretty dangerous profession. I admire those with the guts to do it.

      I just remembered that they don't slide down individually. There's a
      basket they all get into, and THAT slides down the wire. Still sounds
      like a fun ride, as long as there aren't several tons of rocket fuel
      about to explode behind you.

  • The problem was that it was very difficult to get incapacitated people into the basket and down to the safety of the bunker. With the new egress system, healthy workers can just put the wounded in seats and let them ride down to safety.

    Well, that's not difficult at all! So, as long as you have "healthy workers," the problem is mitigated. There's no chance that they will all be incapacitated simultaneously. And all they have to do is pull the wounded to the escape seats, buckle them in, light up their last cigarette, then smash the big red button to begin the speedy 4 minute decent back to the bunker

      In the accidents this system is designed to protect for, it can. This really is not to help out a crew that is strapped into a launch system during terminal count. In that case, the launch abort system is fired and the whole capsule is carried away rapidly. This is actually what happened during Soyuz T-10-1 when it caught fire (link here [wikipedia.org]).

    Putting aside for the moment that the people this is intended for will only be using it in emergency situations, they are also the group of people least likely to appreciate such a "ride" even if it were in casual circumstances. These folks already ride a massive controlled explosion into orbit where they are weightless for a week or more at a time. Compared to that ride this "third highest drop in the world" probably sounds like a day off for their stomachs. ;)
  • I thought I read a while back that NASA was planning a low-friction rails system akin to Final Fantasy 8's Ragnarok launch [youtube.com]. Although I would guess the pitch of the climb would be a bit less dramatic.

    The idea of which of course is building energy instead of a massive short blast. You build up speed over a long distance, and slowly climb to virtical, where the rails end.

    It looks like this track goes straight down along the launch tower, while the old system had wires going from the top of the tower at a shallow angle. It seems to me that the old solution gets you out of the blast radius quicker. It certainly stays farther away from the noisy end of the rocket.
    • by steveo777 (183629)
      Either way, you're relying on that tower to stay standing for at least the first part of your adventure down the track, might as well build up some speed before you hit the independent part. Zip lines can break a lot easier than metal rails (would make sense to me, anyway). I read the article and it doesn't say which system is faster, so I'm going with the roller coaster of actual terror.
      • by StikyPad (445176)
        Also if any part of a zip line breaks, the whole thing is useless. If the top of a structure breaks, the bottom still works, which could make a difference (though probably wouldn't, since any explosion would likely be from the bottom-up anyway).
    • by Leuf (918654)
      We can only see a tiny bit of it so it's hard to draw any conclusions. But I imagine a straight vertical drop at the top would give you faster acceleration while keeping the cost down. You might stay closer to the rocket during the initial few seconds, but for the type of emergency this system is designed for that shouldn't make too much difference. If the fire is in the capsule then getting down is just as good as getting horizontally away, and if the fire is in the rocket itself you're dead before you

      Both Mercury and Apollo [wikipedia.org] had that. In a pre-launch emergency, a solid fuel rocket on an escape tower atop the capsule would fire, explosive bolts would detach the capsule from the booster, and the astronauts would take a very short, high-G ride upward, away from the booster. Then more explosive bolts would detach the esc
